CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119(e) to U.S.Provisional Application Ser. No. 61/118,720 filed Dec. 1, 2008.

FIELD OF INVENTION

The present application relates to perfume raw materials, perfumedelivery systems and consumer products comprising such perfume rawmaterials and/or such perfume delivery systems, as well as processes formaking and using such perfume raw materials, perfume delivery systemsand consumer products.

BACKGROUND OF THE INVENTION

Consumer products may comprise one or more perfumes and/or perfumedelivery systems that can provide a desired scent to such product and/ora situs that is contacted with such a product and/or mask an undesirableodor. While current perfumes and perfume delivery systems providedesirable odors, consumers continue to seek products that have scentsthat may be longer lasting and that are tailored to their individualdesires (see for example USPA 2007/0275866 A1 and U.S. patentapplication Ser. No. 12/133,866)—unfortunately the pool of perfume rawmaterials and perfume delivery systems that is available is still toolimited to completely meet the perfume community's needs. Thus,perfumers need an ever larger pool of perfume raw materials and perfumedelivery systems.

Applicants believe that the perfume raw materials and compositions,including the delivery systems, disclosed herein expand the perfumecommunity's options, as such perfume raw materials can providevariations on character and such compositions can provide desired odorprofiles.

SUMMARY OF THE INVENTION

The present application relates to perfume raw materials, perfumesystems and consumer products comprising such perfume raw materialsand/or such perfume systems, as well as processes for making and usingsuch perfume raw materials, perfume systems and consumer products.

Perfume Delivery Systems

Certain perfume delivery systems, methods of making certain perfumedelivery systems and the uses of such perfume delivery systems aredisclosed in USPA 2007/0275866 A1. Such perfume delivery systemsinclude:

I. Polymer Assisted Delivery (PAD): This perfume delivery technologyuses polymeric materials to deliver perfume materials. Classicalcoacervation, water soluble or partly soluble to insoluble charged orneutral polymers, liquid crystals, hot melts, hydrogels, perfumedplastics, microcapsules, nano- and micro-latexes, polymeric filmformers, and polymeric absorbents, polymeric adsorbents, etc. are someexamples. PAD includes but is not limited to:

-   -   a.) Matrix Systems: The fragrance is dissolved or dispersed in a        polymer matrix or particle. Perfumes, for example, may be 1)        dispersed into the polymer prior to formulating into the product        or 2) added separately from the polymer during or after        formulation of the product. Diffusion of perfume from the        polymer is a common trigger that allows or increases the rate of        perfume release from a polymeric matrix system that is deposited        or applied to the desired surface (situs), although many other        triggers are know that may control perfume release. Absorption        and/or adsorption into or onto polymeric particles, films,        solutions, and the like are aspects of this technology. Nano- or        micro-particles composed of organic materials (e.g., latexes)        are examples. Suitable particles include a wide range of        materials including, but not limited to polyacetal,        polyacrylate, polyacrylic, polyacrylonitrile, polyamide,        polyaryletherketone, polybutadiene, polybutylene, polybutylene        terephthalate, polychloroprene, poly ethylene, polyethylene        terephthalate, polycyclohexylene dimethylene terephthalate,        polycarbonate, polychloroprene, polyhydroxyalkanoate,        polyketone, polyester, polyethylene, polyetherimide,        polyethersulfone, polyethylenechlorinates, polyimide,        polyisoprene, polylactic acid, polymethylpentene, polyphenylene        oxide, polyphenylene sulfide, polyphthalamide, polypropylene,        polystyrene, polysulfone, polyvinyl acetate, polyvinyl chloride,        as well as polymers or copolymers based on        acrylonitrile-butadiene, cellulose acetate, ethylene-vinyl        acetate, ethylene vinyl alcohol, styrene-butadiene, vinyl        acetate-ethylene, and mixtures thereof.        -   “Standard” systems refer to those that are “pre-loaded” with            the intent of keeping the pre-loaded perfume associated with            the polymer until the moment or moments of perfume release.            Such polymers may also suppress the neat product odor and            provide a bloom and/or longevity benefit depending on the            rate of perfume release. One challenge with such systems is            to achieve the ideal balance between 1) in-product stability            (keeping perfume inside carrier until you need it) and 2)            timely release (during use or from dry situs). Achieving            such stability is particularly important during in-product            storage and product aging. This challenge is particularly            apparent for aqueous-based, surfactant-containing products,            such as heavy duty liquid laundry detergents. Many            “Standard” matrix systems available effectively become            “Equilibrium” systems when formulated into aqueous-based            products. One may select an “Equilibrium” system or a            Reservoir system, which has acceptable in-product diffusion            stability and available triggers for release (e.g.,            friction). “Equilibrium” systems are those in which the            perfume and polymer may be added separately to the product,            and the equilibrium interaction between perfume and polymer            leads to a benefit at one or more consumer touch points            (versus a free perfume control that has no polymer-assisted            delivery technology). The polymer may also be pre-loaded            with perfume; however, part or all of the perfume may            diffuse during in-product storage reaching an equilibrium            that includes having desired perfume raw materials (PRMs)            associated with the polymer. The polymer then carries the            perfume to the surface, and release is typically via perfume            diffusion. The use of such equilibrium system polymers has            the potential to decrease the neat product odor intensity of            the neat product (usually more so in the case of pre-loaded            standard system). Deposition of such polymers may serve to            “flatten” the release profile and provide increased            longevity. As indicated above, such longevity would be            achieved by suppressing the initial intensity and may enable            the formulator to use more high impact or low odor detection            threshold (ODT) or low Kovats Index (KI) PRMs to achieve            FMOT benefits without initial intensity that is too strong            or distorted. It is important that perfume release occurs            within the time frame of the application to impact the            desired consumer touch point or touch points. Suitable            micro-particles and micro-latexes as well as methods of            making same may be found in USPA 2005/0003980 A1. Matrix            systems also include hot melt adhesives and perfume            plastics. In addition, hydrophobically modified            polysaccharides may be formulated into the perfumed product            to increase perfume deposition and/or modify perfume            release. All such matrix systems, including for example            polysaccarides and nanolatexes may be combined with other            PDTs, including other PAD systems such as PAD reservoir            systems in the form of a perfume microcapsule (PMC). Polymer            Assisted Delivery (PAD) matrix systems may include those            described in the following references: US Patent            Applications 2004/0110648 A1; 2004/0092414 A1; 2004/0091445            A1 and 2004/0087476 A1; and U.S. Pat. Nos. 6,531,444;            6,024,943; 6,042,792; 6,051,540; 4,540,721 and 4,973,422.        -   Silicones are also examples of polymers that may be used as            PDT, and can provide perfume benefits in a manner similar to            the polymer-assisted delivery “matrix system”. Such a PDT is            referred to as silicone-assisted delivery (SAD). One may            pre-load silicones with perfume, or use them as an            equilibrium system as described for PAD. Suitable silicones            as well as making same may be found in WO 2005/102261; USPA            20050124530A1; USPA 20050143282A1; and WO 2003/015736.            Functionalized silicones may also be used as described in            USPA 2006/003913 A1. Examples of silicones include            polydimethylsiloxane and polyalkyldimethylsiloxanes. Other            examples include those with amine functionality, which may            be used to provide benefits associated with amine-assisted            delivery (AAD) and/or polymer-assisted delivery (PAD) and/or            amine-reaction products (ARP). Other such examples may be            found in U.S. Pat. No. 4,911,852; USPA 2004/0058845 A1; USPA            2004/0092425 A1 and USPA 2005/0003980 A1.    -   b.) Reservoir Systems: Reservoir systems are also known as a        core-shell type technology, or one in which the fragrance is        surrounded by a perfume release controlling membrane, which may        serve as a protective shell. The material inside the        microcapsule is referred to as the core, internal phase, or        fill, whereas the wall is sometimes called a shell, coating, or        membrane. Microparticles or pressure sensitive capsules or        microcapsules are examples of this technology. Microcapsules of        the current invention are formed by a variety of procedures that        include, but are not limited to, coating, extrusion,        spray-drying, interfacial, in-situ and matrix polymerization.        The possible shell materials vary widely in their stability        toward water. Among the most stable are polyoxymethyleneurea        (PMU)-based materials, which may hold certain PRMs for even long        periods of time in aqueous solution (or product). Such systems        include but are not limited to urea-formaldehyde and/or        melamine-formaldehyde. Gelatin-based microcapsules may be        prepared so that they dissolve quickly or slowly in water,        depending for example on the degree of cross-linking. Many other        capsule wall materials are available and vary in the degree of        perfume diffusion stability observed. Without wishing to be        bound by theory, the rate of release of perfume from a capsule,        for example, once deposited on a surface is typically in reverse        order of in-product perfume diffusion stability. As such,        urea-formaldehyde and melamine-formaldehyde microcapsules for        example, typically require a release mechanism other than, or in        addition to, diffusion for release, such as mechanical force        (e.g., friction, pressure, shear stress) that serves to break        the capsule and increase the rate of perfume (fragrance)        release. Other triggers include melting, dissolution, hydrolysis        or other chemical reaction, electromagnetic radiation, and the        like. The use of pre-loaded microcapsules requires the proper        ratio of in-product stability and in-use and/or on-surface        (on-situs) release, as well as proper selection of PRMs.        Microcapsules that are based on urea-formaldehyde and/or        melamine-formaldehyde are relatively stable, especially in near        neutral aqueous-based solutions. These materials may require a        friction trigger which may not be applicable to all product        applications. Other microcapsule materials (e.g., gelatin) may        be unstable in aqueous-based products and may even provide        reduced benefit (versus free perfume control) when in-product        aged. Scratch and sniff technologies are yet another example of        PAD. Perfume microcapsules (PMC) may include those described in        the following references: US Patent Applications: 2003/0125222        A1; 2003/215417 A1; 2003/216488 A1; 2003/158344 A1; 2003/165692        A1; 2004/071742 A1; 2004/071746 A1; 2004/072719 A1; 2004/072720        A1; 2006/0039934 A1; 2003/203829 A1; 2003/195133 A1; 2004/087477        A1; 2004/0106536 A1; and U.S. Pat. Nos. 6,645,479 B1; 6,200,949        B1; 4,882,220; 4,917,920; 4,514,461; 6,106,875 and 4,234,627,        3,594,328 and US RE 32713.        II. Molecule-Assisted Delivery (MAD): Non-polymer materials or        molecules may also serve to improve the delivery of perfume.        Without wishing to be bound by theory, perfume may        non-covalently interact with organic materials, resulting in        altered deposition and/or release. Non-limiting examples of such        organic materials include but are not limited to hydrophobic        materials such as organic oils, waxes, mineral oils, petrolatum,        fatty acids or esters, sugars, surfactants, liposomes and even        other perfume raw material (perfume oils), as well as natural        oils, including body and/or other soils. Perfume fixatives are        yet another example. In one aspect, non-polymeric materials or        molecules have a CLogP greater than about 2. Molecule-Assisted        Delivery (MAD) may also include those described in U.S. Pat. No.        7,119,060 and U.S. Pat. No. 5,506,201.        III. Fiber-Assisted Delivery (FAD): The choice or use of a situs        itself may serve to improve the delivery of perfume. In fact,        the situs itself may be a perfume delivery technology. For        example, different fabric types such as cotton or polyester will        have different properties with respect to ability to attract        and/or retain and/or release perfume. The amount of perfume        deposited on or in fibers may be altered by the choice of fiber,        and also by the history or treatment of the fiber, as well as by        any fiber coatings or treatments. Fibers may be woven and        non-woven as well as natural or synthetic. Natural fibers        include those produced by plants, animals, and geological        processes, and include but are not limited to cellulose        materials such as cotton, linen, hemp jute, flax, ramie, and        sisal, and fibers used to manufacture paper and cloth.        Fiber-Assisted Delivery may consist of the use of wood fiber,        such as thermomechanical pulp and bleached or unbleached kraft        or sulfite pulps. Animal fibers consist largely of particular        proteins, such as silk, sinew, catgut and hair (including wool).        Polymer fibers based on synthetic chemicals include but are not        limited to polyamide nylon, PET or PBT polyester,        phenol-formaldehyde (PF), polyvinyl alcohol fiber (PVOH),        polyvinyl chloride fiber (PVC), polyolefins (PP and PE), and        acrylic polymers. All such fibers may be pre-loaded with a        perfume, and then added to a product that may or may not contain        free perfume and/or one or more perfume delivery technologies.        In one aspect, the fibers may be added to a product prior to        being loaded with a perfume, and then loaded with a perfume by        adding a perfume that may diffuse into the fiber, to the        product. Without wishing to be bound by theory, the perfume may        absorb onto or be adsorbed into the fiber, for example, during        product storage, and then be released at one or more moments of        truth or consumer touch points.        IV. Amine Assisted Delivery (AAD): The amine-assisted delivery        technology approach utilizes materials that contain an amine        group to increase perfume deposition or modify perfume release        during product use. There is no requirement in this approach to        pre-complex or pre-react the perfume raw material(s) and amine        prior to addition to the product. In one aspect,        amine-containing AAD materials suitable for use herein may be        non-aromatic; for example, polyalkylimine, such as        polyethyleneimine (PEI), or polyvinylamine (PVAm), or aromatic,        for example, anthranilates. Such materials may also be polymeric        or non-polymeric. In one aspect, such materials contain at least        one primary amine. This technology will allow increased        longevity and controlled release also of low ODT perfume notes        (e.g., aldehydes, ketones, enones) via amine functionality, and        delivery of other PRMs, without being bound by theory, via        polymer-assisted delivery for polymeric amines. Without        technology, volatile top notes can be lost too quickly, leaving        a higher ratio of middle and base notes to top notes. The use of        a polymeric amine allows higher levels of top notes and other        PRMS to be used to obtain freshness longevity without causing        neat product odor to be more intense than desired, or allows top        notes and other PRMs to be used more efficiently. In one aspect,        AAD systems are effective at delivering PRMs at pH greater than        about neutral. Without wishing to be bound by theory, conditions        in which more of the amines of the AAD system are deprotonated        may result in an increased affinity of the deprotonated amines        for PRMs such as aldehydes and ketones, including unsaturated        ketones and enones such as damascone. In another aspect,        polymeric amines are effective at delivering PRMs at pH less        than about neutral. Without wishing to be bound by theory,        conditions in which more of the amines of the AAD system are        protonated may result in a decreased affinity of the protonated        amines for PRMs such as aldehydes and ketones, and a strong        affinity of the polymer framework for a broad range of PRMs. In        such an aspect, polymer-assisted delivery may be delivering more        of the perfume benefit; such systems are a subspecies of AAD and        may be referred to as Amine-Polymer-Assisted Delivery or APAD.        In some cases when the APAD is employed in a composition that        has a pH of less than seven, such APAD systems may also be        considered Polymer-Assisted Delivery (PAD). In yet another        aspect, AAD and PAD systems may interact with other materials,        such as anionic surfactants or polymers to form coacervate        and/or coacervates-like systems. In another aspect, a material        that contains a heteroatom other than nitrogen, for example        sulfur, phosphorus or selenium, may be used as an alternative to        amine compounds. In yet another aspect, the aforementioned        alternative compounds can be used in combination with amine        compounds. In yet another aspect, a single molecule may comprise        an amine moiety and one or more of the alternative heteroatom        moieties, for example, thiols, phosphines and selenols. Suitable        AAD systems as well as methods of making same may be found in US        Patent Applications 2005/0003980 A1; 2003/0199422 A1;        2003/0036489 A1; 2004/0220074 A1 and U.S. Pat. No. 6,103,678.        V. Cyclodextrin Delivery System (CD): This technology approach        uses a cyclic oligosaccharide or cyclodextrin to improve the        delivery of perfume. Typically a perfume and cyclodextrin (CD)        complex is formed. Such complexes may be preformed, formed        in-situ, or formed on or in the situs. Without wishing to be        bound by theory, loss of water may serve to shift the        equilibrium toward the CD-Perfume complex, especially if other        adjunct ingredients (e.g., surfactant) are not present at high        concentration to compete with the perfume for the cyclodextrin        cavity. A bloom benefit may be achieved if water exposure or an        increase in moisture content occurs at a later time point. In        addition, cyclodextrin allows the perfume formulator increased        flexibility in selection of PRMs. Cyclodextrin may be pre-loaded        with perfume or added separately from perfume to obtain the        desired perfume stability, deposition or release benefit.        Suitable CDs as well as methods of making same may be found in        USPA 2005/0003980 A1 and 2006/0263313 A1 and U.S. Pat. Nos.        5,552,378; 3,812,011; 4,317,881; 4,418,144 and 4,378,923.        VI. Starch Encapsulated Accord (SEA): The use of a starch        encapsulated accord (SEA) technology allows one to modify the        properties of the perfume, for example, by converting a liquid        perfume into a solid by adding ingredients such as starch. The        benefit includes increased perfume retention during product        storage, especially under non-aqueous conditions. Upon exposure        to moisture, a perfume bloom may be triggered. Benefits at other        moments of truth may also be achieved because the starch allows        the product formulator to select PRMs or PRM concentrations that        normally cannot be used without the presence of SEA. Another        technology example includes the use of other organic and        inorganic materials, such as silica to convert perfume from        liquid to solid. Suitable SEAs as well as methods of making same        may be found in USPA 2005/0003980 A1 and U.S. Pat. No. 6,458,754        B1.        VII. Inorganic Carrier Delivery System (ZIC): This technology        relates to the use of porous zeolites or other inorganic        materials to deliver perfumes. Perfume-loaded zeolite may be        used with or without adjunct ingredients used for example to        coat the perfume-loaded zeolite (PLZ) to change its perfume        release properties during product storage or during use or from        the dry situs. Suitable zeolite and inorganic carriers as well        as methods of making same may be found in USPA 2005/0003980 A1        and U.S. Pat. Nos. 5,858,959; 6,245,732 B1; 6,048,830 and        4,539,135. Silica is another form of ZIC. Another example of a        suitable inorganic carrier includes inorganic tubules, where the        perfume or other active material is contained within the lumen        of the nano- or micro-tubules. In one aspect, the perfume-loaded        inorganic tubule (or Perfume-Loaded Tubule or PLT) is a mineral        nano- or micro-tubule, such as halloysite or mixtures of        halloysite with other inorganic materials, including other        clays. The PLT technology may also comprise additional        ingredients on the inside and/or outside of the tubule for the        purpose of improving in-product diffusion stability, deposition        on the desired situs or for controlling the release rate of the        loaded perfume. Monomeric and/or polymeric materials, including        starch encapsulation, may be used to coat, plug, cap, or        otherwise encapsulate the PLT. Suitable PLT systems as well as        methods of making same may be found in U.S. Pat. No. 5,651,976.        VIII. Pro-Perfume (PP): This technology refers to perfume        technologies that result from the reaction of perfume materials        with other substrates or chemicals to form materials that have a        covalent bond between one or more PRMs and one or more carriers.        The PRM is converted into a new material called a pro-PRM (i.e.,        pro-perfume), which then may release the original PRM upon        exposure to a trigger such as water or light. Pro-perfumes may        provide enhanced perfume delivery properties such as increased        perfume deposition, longevity, stability, retention, and the        like. Pro-perfumes include those that are monomeric        (non-polymeric) or polymeric, and may be pre-formed or may be        formed in-situ under equilibrium conditions, such as those that        may be present during in-product storage or on the wet or dry        situs. Nonlimiting examples of pro-perfumes include Michael        adducts (e.g., beta-amino ketones), aromatic or non-aromatic        imines (Schiff bases), oxazolidines, beta-keto esters, and        orthoesters. Another aspect includes compounds comprising one or        more beta-oxy or beta-thio carbonyl moieties capable of        releasing a PRM, for example, an alpha, beta-unsaturated ketone,        aldehyde or carboxylic ester. The typical trigger for perfume        release is exposure to water; although other triggers may        include enzymes, heat, light, pH change, autoxidation, a shift        of equilibrium, change in concentration or ionic strength and        others. For aqueous-based products, light-triggered pro-perfumes        are particularly suited. Such photo-pro-perfumes (PPPs) include        but are not limited to those that release coumarin derivatives        and perfumes and/or pro-perfumes upon being triggered. The        released pro-perfume may release one or more PRMs by means of        any of the above mentioned triggers. In one aspect, the        photo-pro-perfume releases a nitrogen-based pro-perfume when        exposed to a light and/or moisture trigger. In another aspect,        the nitrogen-based pro-perfume, released from the        photo-pro-perfume, releases one or more PRMs selected, for        example, from aldehydes, ketones (including enones) and        alcohols. In still another aspect, the PPP releases a dihydroxy        coumarin derivative. The light-triggered pro-perfume may also be        an ester that releases a coumarin derivative and a perfume        alcohol. In one aspect the pro-perfume is a dimethoxybenzoin        derivative as described in USPA 2006/0020459 A1. In another        aspect the pro-perfume is a 3′, 5′-dimethoxybenzoin (DMB)        derivative that releases an alcohol upon exposure to        electromagnetic radiation. In yet another aspect, the        pro-perfume releases one or more low ODT PRMs, including        tertiary alcohols such as linalool, tetrahydrolinalool, or        dihydromyrcenol. Suitable pro-perfumes and methods of making        same can be found in U.S. Pat. Nos. 7,018,978 B2; 6,987,084 B2;        6,956,013 B2; 6,861,402 B1; 6,544,945 B1; 6,093,691; 6,277,796        B1; 6,165,953; 6,316,397 B1; 6,437,150 B1; 6,479,682 B1;        6,096,918; 6,218,355 B1; 6,133,228; 6,147,037; 7,109,153 B2;        7,071,151 B2; 6,987,084 B2; 6,610,646 B2 and 5,958,870, as well        as can be found in USPA 2005/0003980 A1 and USPA 2006/0223726        A1.    -   Amine Reaction Product (ARP): For purposes of the present        application, ARP is a subclass or species of PP. One may also        use “reactive” polymeric amines in which the amine functionality        is pre-reacted with one or more PRMs to form an amine reaction        product (ARP). Typically the reactive amines are primary and/or        secondary amines, and may be part of a polymer or a monomer        (non-polymer). Such ARPs may also be mixed with additional PRMs        to provide benefits of polymer-assisted delivery and/or        amine-assisted delivery. Nonlimiting examples of polymeric        amines include polymers based on polyalkylimines, such as        polyethyleneimine (PEI), or polyvinylamine (PVAm). Nonlimiting        examples of monomeric (non-polymeric) amines include        hydroxylamines, such as 2-aminoethanol and its alkyl substituted        derivatives, and aromatic amines such as anthranilates. The ARPs        may be premixed with perfume or added separately in leave-on or        rinse-off applications. In another aspect, a material that        contains a heteroatom other than nitrogen, for example oxygen,        sulfur, phosphorus or selenium, may be used as an alternative to        amine compounds. In yet another aspect, the aforementioned        alternative compounds can be used in combination with amine        compounds. In yet another aspect, a single molecule may comprise        an amine moiety and one or more of the alternative heteroatom        moieties, for example, thiols, phosphines and selenols. The        benefit may include improved delivery of perfume as well as        controlled perfume release. Suitable ARPs as well as methods of        making same can be found in USPA 2005/0003980 A1 and U.S. Pat.        No. 6,413,920 B1.

Then, the reaction mixture was stirred whilst thetemperature of the oil bath was increased to 115-130° C. Aliquots of thereaction mixture were removed by syringe and analyzed by GC-FID. Basedon the GC-results, the reaction was allowed to progress (in thisspecific case) until 85% of the starting material was converted over aperiod of 7 days.
